If you have a body lift, there will be "pucks" in between the body and the frame. Typically, these pucks look like hockey pucks (thus the name "pucks") and come in the 1", 2" or 3" variety. I think that M.O.R.E. makes theirs in aluminum, so instead of being black, they may be silver in color. As far as the SYE, do a search for SYE's and CV driveshaft's and compare your transfer case and rear driveshaft to your search results.
I feel sorry for people who don't drink. When they wake up in the morning, that's as good as they're going to feel all day. --Frank Sinatra
